Systems and methods for pre-scanning merchandise in customer&#39;s shopping cart while customer is waiting in checkout line

ABSTRACT

A mobile scanning station for pre-scanning retail merchandise includes a frame, and a pair of arms mounted to the frame, positioned to hold an open bag for receiving pre-scanned items. A platform is mounted to the frame, positioned under the pair of arms for providing a supporting surface for items contained in an open bag held by the pair of arms. The frame further includes an EAS deactivator support for holding an EAS deactivator for deactivating EAS tags on pre-scanned items before they are placed in the open bag. In a method for pre-scanning retail merchandise, a mobile pre-scanning station is positioned proximate to a shopping cart of a retail customer waiting in a checkout line, and a transaction identifier card is scanned. Bar-coded items from the customer&#39;s shopping cart are then scanned. If the scanned item has an EAS tap, an EAS deactivator seated in the mobile pre-scanning station is used to deactivate the EAS tag. The scanned item is then placed into a bag held open by the pre-scanning station.

DETAILED DESCRIPTION

Aspects of the present invention provide systems and methods forproviding spot assistance in the checkout process. These systems andmethods are collectively referred to herein as the Line Rusher™ system.As described below, an aspect of the invention provides a mobilepre-scanning station, operated by a first store employee, which is usedin conjunction with a checkout terminal, operated by a second storeemployee. While a customer is standing in line waiting to be checked outat the checkout terminal, the mobile pre-scanning station is used toperform certain checkout functions for some or all of the merchandise inthe customer's cart. The checkout process is subsequently completed atthe checkout terminal when the customer reaches the cashier at the headof the checkout line.

A typical retail checkout process not using a mobile pre-scanningstation may include the following functions performed at a checkoutterminal:

1. Examining each item to be purchased to determine whether the itembears a bar code;

2. Using a scanning unit to scan bar codes on bar-coded items;

3. Using a keypad to manually key in items that are not bar-coded;

4. Deactivating electronic article surveillance (EAS) tags affixed toitems to be purchased;

5. Once all of the items have either been scanned or manually keyed in,processing payment, including any coupons or other store promotions; and

6. Bagging the purchased items.

According to an aspect of the invention, the above checkout process ismodified so that certain functions are performed at a mobile stationwhile the customer is standing in a checkout line, and certain otherfunctions are performed at the permanent checkout station. The functionsperformed at the mobile station include:

1. Looking in the shopper's cart and identifying bar-coded items;

2. Using a wireless handheld scanning unit to pre-scan bar-coded itemsand storing the scan data in the store's checkout system;

3 . Using a portable EAS deactivating unit to deactivate EAS tags on thepre-scanned items; and

4. Bagging the pre-scanned, EAS-deactivated items.

The functions performed at the permanent checkout stations include thefollowing:

1. Retrieving the stored pre-scan data;

2. Manually keying in items that have not been pre-scanned, deactivatingEAS tags on these items, and then bagging them; and

3. Processing payment, including coupons and other store promotions.

Thus, it will be seen that the relatively time-consuming processes ofscanning bar-coded items in the shopper's cart and deactivating the EAStags on these items is performed while the customer is standing in line.Further aspects of the invention will be understood in light of thefollowing description.

FIGS. 1, 2 and 3 show, respectively, front, side, and rear elevationviews of a cart 10 according to a first aspect of the invention. Asdescribed below, the cart 10 provides a mechanical framework for theLine Rusher™ system. The cart 10 is designed to combine stability with asmall footprint. In particular, the cart 10 is designed not to tip over,even when it is fully loaded. However, its relatively small size allowsthe cart 10 to be readily maneuvered into position, even when the storeis crowded, and to be easily stored when it is not in use.

The frame of the cart 10 includes a handle 12, a pair of side posts 14extending downward from either end of the handle 12, a pair of legs 16extending downward at a rearward angle from the lower ends of side posts14, a pair of ankles 18 extending downward at a forward angle from thelower ends of the legs 16, and a pair of feet 20, extending forward fromthe lower ends of the ankles 18.

An arm unit 30 is mounted to the front of the side posts 14. The armunit includes a pair of arms 32 that project forward, an upper crossbar34, and a lower crossbar 36. The upper crossbar 34 has fabricatedthereon a first slot 38 and a second slot 40 on either side of a centralpost 42. Fabricated onto the rear of the side posts 14 under the armunit 30 are a pair of hooks 44 that, as described further below, may beused to hold bags of pre-scanned items, as needed. There is mounted tothe lower end of the side posts 14 a platform unit 50, that includes aforwardly projecting platform 52, and a mounting bracket 54. A pair ofbraces 60 is mounted onto the cart 10 between the lower end of the sideposts 14, and the front end of the feet 20. A rectangular basket 62 ismounted between the feet 20, and a pair of axles 64 extends outward fromeach ankle 18. In the finished cart, wheels, not shown in FIGS. 1-3, aremounted onto the axles 64.

The above-described components are dimensioned and angled with respectto each other such that, when the cart 10 is in its normal, standingposition, the arms 32 and platform 52 are substantially horizontal, withthe platform 52 positioned underneath the arms 32. As described infurther detail below, the arms 32, platform 52, and post 42 are used tohold a shopping bag. As further described below, the upper crossbar 34and slots 38 and 40 are positioned relative to the handle 12 to allow aportable EAS deactivation unit to be seated in slot 40 and held betweenthe crossbar 34 and the handle 12, and to allow a cardholder affixed toslot 38 to be easily accessed by a person using the cart 10.

The cardholder affixed to slot 38 is used to hold transaction identifiercards, referred to herein as Line Rusher™ cards. FIG. 4 shows anelevation view of a Line Rusher™ card 80 according to an aspect of theinvention. The card 80 is approximately the size and shape of a creditcard and bears a unique bar code 82 that is used to identify thepre-scan information to the system for subsequent retrieval at thecheckout terminal.

Returning to FIGS. 1-3, the side posts 14 of the cart 10 aresubstantially vertical and are positioned so that they are approximatelyover the center of gravity of the cart 10 so that the cart is stablewhen it is at rest in its normal standing position. The wheels affixedto the axles 18 are dimensioned so that the wheels engage the floor whenthe cart is tipped backwards, but are clear of the floor when the cartis in its normal standing position so the cart 10 does not move after ithas been rolled to a desired location. According to a further aspect ofthe invention, additional footing elements, such as small sphericalknobs, may be affixed to the bottom of the feet 20 for increasedstability.

The handle 12, side posts 14, legs 16, ankles 18, and feet 20 may befabricated from a single length of metal tubing, which is bent orotherwise shaped to form these elements. Plugs may be inserted intoeither end of the tubing to close off the tube openings. The arm unit 30may be fabricated from a single length of metal tubing or from a metalrod that is bent or otherwise shaped to form the arms and crossbars. Theslots 38 and 40 and central post 42 may be separately manufactured andthen welded or otherwise mounted onto the top crossbar 34 of the armunit 30.

The platform bracket 54 may be fabricated from a single length of metaltubing or from a metal rod that is bent or otherwise shaped to form thebracket. The platform 52 may be fabricated separately from a sheet ofmetal that is cut and then mounted to the bracket 54. Once the platform52 has been mounted to the bracket 54, the resulting platform unit 50may then be welded or otherwise mounted to the side posts 14. Accordingto a further aspect of the invention, there may be provided at the rearof the platform 52 a rectangular cutout section 56, not shown in FIGS.1-3 but seen in FIG. 12, extending across the platform under the armunit crossbars 34 and 36. As described further below, the cutout sectionis dimensioned and positioned to receive the bottom portion of a bagstack mounted into the cart.

The braces 60 may be separately fabricated from strips of metal thathave been bent or otherwise formed into a suitable shape. Once formed,the brackets 60 are then welded or otherwise mounted to the side posts14 and feet 20. The wire basket 62 is also separately fabricated andthen welded or otherwise mounted between the feet 20. The axles 64 maybe fabricated as separate units and then welded or otherwise mounted tothe ankles 18. Alternatively, holes may be provided through the ankles18, and the axles 64 may be provided by bolts that are threaded throughthe holes.

Suitable dimensions for the cart 10 include the following:

Overall Height: 42″ Arm Height: 36.875″ Arm Length: 9.125″ Back HookHeight: 32″ Platform Height: 25.5″ Platform Length: 9.375″ PlatformCutout Width: 2″ Brace Length: 20.5″ Angle between Side Posts and Legs:160° Angle between Legs and Feet: 70° Base of Frame: 12.5″ (width) ×15.5″ (length) Wheel Base: 16.375″ (axle tip to axle tip) Axle BoltLength: 1.5″ Wheel Radius: 1.468″

FIG. 5 shows an elevation view of a bag stack 100 suitable for use inthe Line Rusher™ system, and FIG. 6 shows a cross section of the bagstack 100 through the plane 6-6. As shown in FIGS. 5 and 6, the stack100 includes a plurality of individual shopping bags 102 stacked on topof each other, and attached to each other at a number of spot welds 104.The welds 104 are designed to release when bags 102 are pulled apartfrom each other. The bag stack 100 may suitably be fabricated from aplastic material using thermoforming and die cutting techniques.

Each bag 102 in the stack 100 includes a pair of handles 106 and a pouch108. Each handle includes a slit 110 for receiving a support arm, suchas the arms 32 shown in FIGS. 1 through 3, and a heart-shaped flap 112that pulls back to form an opening that fits over a central post, suchas the post 42 shown in FIGS. 1-3. The slits 110 are shaped andpositioned such that they away to release the handles 104 from thesupport arms 32. In addition, a center slit 114 is provided on top ofthe heart-shaped flap 112 to allow the bag to be torn away from thecentral post 42. As shown in FIG. 6, each bag includes front and backpanels 120 and 122, side pleats 124 that unfold when the bag 102 isopened.

Thus, in preparing the cart shown in FIGS. 1-3 for use, a bag stack,such as the bag stack 100 shown in FIGS. 5 and 6, is loaded onto thecart 10 by inserting the supporting arms 32 through the handle slits104, and fitting the flapped opening 112 over the central post 42. Thebags 102 are dimensioned so that when the stack of bags 100 is loadedonto the support arms 32 and central post 42, the bottom of the pouch108 may be tucked into the rectangular cutout at the rear of platform52. The bottom of the bag stack 100 is then held in position in theplatform cutout by the platform 52 and the platform bracket 54.

A bag 102 is prepared for loading by pulling the front panel 120 of thetop bag in the stack 100 forwards. The rear panel 122 is held in placeby the post 42, and the bag handles 106 are held up by the arms 32. Thebottom of the pouch 108 rests on the platform 52. Thus, as the bag isbeing loaded with pre-scanned items, the weight of these items is bornemostly by the platform 52, rather than by the arms 32. This arrangementserves a number of functions. First, it makes it easier for a user ofthe cart to hold a bag in a fully open position, even after items havebeen placed in the bag. Further, minimizing the weight borne by the arms32 tends to prevent a bag 102 from prematurely releasing from the arms32 and post 42 during the bagging process and allows a bag 102 to beeasily released from the arms 32 and post 42, even when the contents ofthe bag 102 are unusually heavy or bulky.

FIGS. 7, 8 and 9 show, respectively, perspective, bottom, and side viewsof a portable EAS deactivation unit 200 suitable for use in the LineRusher™ system. The deactivation unit 200 includes a deactivationsurface 202. When an EAS tag is passed proximate to the deactivationsurface 202, the EAS tag is deactivated. As shown in FIG. 8, the EASdeactivation unit 200 includes a tab 204, which is used to lock the unit200 into a security base (not shown). The tab 204 is also used in theLine Rusher™ system to hold the deactivation unit 200 in position on acart, such as the cart 10 shown in FIGS. 1-3. As shown in FIG. 9, thetab 204 is seated in slot 40 of the cart 10. The back of the head of thedeactivation unit 200 rests against the cart handle 12. As described infurther detail below, the position of the EAS deactivation unit 200 onthe cart 10 allows a user of the cart 10 to use one hand to operate ascanning gun and to use the other hand to remove an item to bepre-scanned from a customer's cart, deactivate an EAS tag on thepre-scanned item, and place the item in a shopping bag.

FIG. 10 shows a perspective view and FIG. 11 show shows a side view of awireless handheld scanning unit 250 suitable for use with the LineRusher™ system. The scanning unit may be hung over the handle 12 of thecart 10, or may be carried separately by the employee. It should benoted that other types of scanning units may be used without departingfrom the spirit of the invention.

FIG. 12 shows a front perspective view and FIG. 13 shows a rearperspective view of the above-described components loaded onto a cart10. FIG. 13 further illustrates the cardholder 260, which is used tohold Line Rusher™ cards. FIG. 14 shows a perspective view of the cart 10that has been tipped backward to allow the wheels 270 to engage thefloor, and to allow the cart to be rolled into position by a storeemployee. As described above, when the cart 10 is in its normal,standing position, the wheels 270 do not engage the floor at all. Ifnecessary, the store employee may place his or her foot at the rear ofthe cart's basket 62 to provide a steady pivot axis for the cart 10 asit is tipped backwards. As shown in FIG. 15, the EAS deactivation unit200 is conveniently located to deactivate each pre-scanned item 280before it is bagged. FIG. 16 shows the Line Rusher™ cart 10 with bags ofpre-scanned merchandise 290 hanging from the back hooks 44.

FIG. 17 shows a diagram of a portion of a checkout area 300 in a retailstore. The checkout area 300 includes a checkout lane, which is definedon its left side by a first stack display 306, a first display rack 306,a first conveyor belt 308, and a first bagging carousel 310. Behind thefirst conveyor belt 308 is a second display rack 312 and a point-of-sale(POS) terminal 314 operated by a cashier C. The right side of thecheckout lane 302 is defined by a second stack display 316, a thirddisplay rack 318, a fourth display rack 320, a second POS terminal 322,and a second bagging carousel 326. A second conveyor belt 326 Is locatedon the far side of display rack 320 and POS terminal 322. In thecheckout area 300 shown in FIG. 17, the first and second display racks306 and 312 are used to display merchandise to a shopper in the leftneighboring lane, not shown. The second POS terminal 322, baggingcarousel 324 and conveyor belt 326 are used to serve customers using theright neighboring checkout lane, not shown. In the checkout area shownin FIG. 17, shoppers gain access to a checkout lane 302 through a regionof the store known as “action alley” 328.

As shown in FIG. 17, there are three shoppers S1, S2, and S3 standing inthe checkout lane 302, each pushing a cart. A member of management M,sales associate, or other store employee with a Line Rusher™ cart LRroams among checkout lanes looking for a shopper in need of assistance.In the particular checkout area configuration shown, the manager M mayfind it easier to position the Line Rusher™ cart LR proximate to thethird shopper S3 in line, or to shoppers in line behind the thirdshopper S3. However, it should be noted that, depending upon theconfiguration of a particular store's checkout area, differentprocedures can be used to implement the Line Rusher™ system.

FIG. 18 shows a flowchart of a method 400 according to an aspect of theinvention. In step 402, the Line Rusher™ mobile scanning station isprepared for use. The preparation of the scanning station includesloading a stack of shopping bags onto the support arms 32 and post 42 ofthe cart 10, positioning an EAS deactivation unit 200 in slot 40 oncrossbar 34, and making sure that there are Line Rusher™ cards 80 in thecardholder 260. In addition, the sales associate obtains a handheldscanning unit 250, which can be hung over the crossbar, or carried bythe sales associate.

In step 404, the sales associate roams among checkout lanes, looking fora customer in need of assistance. In step 406, when this customer isfound, the Line Rusher™ cart is placed into a convenient locationproximate to the customer's cart. In step 408, the sales associateprepares a bag on the Line Rusher™ cart by pulling its front panelforward. In step 408, the sales associate takes a Line Rusher™ card outof the cardholder and scans the bar code printed thereon using thehandheld scanning unit. The sales associate may give the Line Rusher™card to the customer, or may hold onto it for safekeeping until thepre-scanning function has been completed. In step 410, the salesassociate finds a bar-coded item in the shopper's cart and removes it.In step 412, the sales associate scans the item using the hand scanner.In step 414, if the pre-scanned item has an EAS tag, the sales associatedeactivates the EAS tag by rubbing it against the deactivation surfaceof the deactivation unit. In step 416, the pre-scanned, deactivated itemis then placed into the bag.

In step 418, it is determined whether the bag is full. If so, then instep 420, the associate removes the bag and puts it to the side, forexample by hanging it on a back hook of the Line Rusher™ cart.Alternatively, bags of pre-scanned items may be placed in the customer'scart, if there is sufficient room. If the bag is not full, the salesassociate in step 422 determines whether there are more bar-coded itemsin the shopper's cart. If so, the associate returns to step 410 andproceeds to pre-scan and deactivate the next bar-coded item in the cart.If there are no more items to be pre-scanned, then in step 424, thesales associate finalizes the pre-scanning operation then gives the bagsof pre-scanned goods to the customer. The pre-scanning operation may befinalized, for example, by making a suitable key input into the keypadon the back of the scanning gun 250. If the customer has not alreadybeen given the Line Rusher™ card, it is given to the customer at the endof the pre-scanning process. It should be noted that the keypad anddisplay on the back of the scanning gun 250 may also be used to edit thelist of scanned items or even, if necessary, to void out the transactionentirely.

In step 426, the customer gives the Line Rusher™ card to the cashier atthe checkout station. In step 428, the cashier scans the Line Rusher™card at the checkout terminal, manually keys in any non-bar-coded items,deactivates these items, and then bags them. In step 430, the cashierhandles payment and any promotions or coupons. It should be noted thatall transactions in which the Line Rusher™ system is used may be voidedout of the system at any time, similar to the way in which normaltransactions are voided out. A Line Rusher™ transaction may be voidedeither using the handheld scanning gun 250, or at the checkout terminal.

It is contemplated that the store employee will generally use one handto operate the scanning unit, and use the other hand to handle thebar-coded items to be scanned. Particularly where small items arescanned, it will be seen that the store employee can pick up the item,scan it, deactivate it, and bag it, without having to put the scanninggun down. However, where the store employee needs the use of both hands,the employee may temporarily put the scanning gun down to free up bothhands. For example, the employee may temporarily place the scanning gunin the customer's cart. Alternatively, the scanning gun may be hung froma belt or otherwise temporarily attached to the person operating theLine Rusher™ cart.

It will be apparent that the invention may be freely modified withoutdeparting from the spirit of the invention. For example, the size andshape of the mobile scanning cart may be modified to accommodatedifferent store environments. It would also be possible to use othertypes of scanning devices in conjunction with the cart, or to attachadditional devices, as desired.

It is contemplated that Line Rusher™ cards will be reusable. Once a LineRusher™ transaction has been completed, or voided, any stored dataassociated with the bar-coded number on the Line Rusher™ card is resetto zero. The card is the available for reuse. However, it would also bewithin the spirit of the invention to use a disposable Line Rusher™ cardthat is only used once. Line Rusher™ cards are bar coded using standardprinting techniques. It would also be possible to use other types ofcards or techniques to identify the pre-scanned items.

From the above description, it will be seen that the present inventionprovides a useful way of enhancing a retail store's checkout capacity.The invention allows a sales associate to roam freely among multiplecheckout lines, searching for customers that might benefit from the LineRusher™ system. Alternatively, once a suitable location is found, theLine Rusher™ cart may remain in position for an extended period of timein order to speed up the checkout process.

Once the retail checkout lines have died down, the cart is rolled out ofthe way. Because the cart is relatively small, it can be easily storedin an unobtrusive location, utilizing a small amount of storage space.Further, it will be seen that the Line Rusher™ system may be used atlocations other than at the main checkout counters.

It will further be appreciated that the Line Rusher™ cart allows a salesassociate, or other store employee, to easily handle and transport allof the components required to perform the above-described pre-scanningoperation. As described above, the pre-scanning operation requires asales associate to handle a scanning gun, an EAS deactivation unit, LineRusher™ card, and a bagging assembly. Without a Line Rusher™ cart, itwould be difficult for a sales associate to perform the pre-scanningfunction in an efficient manner.

In addition, the Line Rusher™ cart secures all of the peripheralsrequired for pre-scanning so that the cart may be freely rolled around aretail store. Once each peripheral has been properly seated into itsdesignated location on the cart, a sales associate may quickly andeasily transport the cart to wherever it may be needed, without any ofthe peripheral components dangling in harm's way or falling out of thecart.

While the foregoing description includes details which will enable thoseskilled in the art to practice the invention, it should be recognizedthat the description is illustrative in nature and that manymodifications and variations thereof will be apparent to those skilledin the art having the benefit of these teachings.
